Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Minocycline is a semisynthetic tetracycline antibiotic that inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit, preventing the addition of amino acids to the elongating peptide chain. This action is bacteriostatic. In periodontal disease, it also inhibits matrix metalloproteinases (MMPs), particularly collagenase, and suppresses inflammatory cytokine production, reducing tissue destruction.

1 mg subgingival application per periodontal pocket, applied as a single dose by a dental professional.
250-500 mg PO q6h or 500 mg to 1 g IV q6h; maximum 4 g/day

The terminal elimination half-life of minocycline is 11-17 hours (mean ~16 hours). This long half-life allows for twice-daily dosing in systemic use, but for Arestin (subgingival), local sustained release provides prolonged local exposure.
Terminal elimination half-life is 6-8 hours in patients with normal renal function. Half-life is significantly prolonged (up to 80 hours) in anuria, requiring dose adjustment.
Minocycline is primarily eliminated via hepatic metabolism and biliary/fecal excretion. Renal excretion accounts for approximately 10-20% of the dose, with the remainder excreted in feces via bile. Less than 10% is recovered unchanged in urine.
Primarily renal excretion of unchanged drug via glomerular filtration; 80-90% recovered in urine within 24 hours. Biliary/fecal excretion accounts for <5%.
